Netconan is an interesting Github project to remove sensitive information from Network configuration files. This is particularly useful in managed SP environment where we share configurations with the end-customer, usually in form of an LLD or SLD.
Netconan can anonymize many types of sensitive information:

  • Sensitive strings like passwords or SNMP community strings for many common network vendors.
  • IPv4 and IPv6 addresses
  • User-specified sensitive words
  • User-specified AS numbers

Netconan is maintained by the same company as Batfish, an interesting open source modeling tool.
